The aria or song is taken from the opera Rinaldo which first appeared in 1711 and was revised in 1733.
It is in ABA form and based on the sarabande rhythm which has the stress on the second beat of the three beats in the bar. When sung the Da Capo section would be an opportunity for the soloist to improvise and ornament the melody and this is option available to the organists although it is important to keep to the style and mood of the piece. This is very appropriate music for a solemn processional in an organ playing context. The use of three registrations is suggested and are indicated in the score. Rests have been indicated in all parts so that players have a clear understanding of the voicing. It is also a movement that invites interpretation and playing in different contexts. The arrangement is in the original key of F major although the tempo for the organ solo is more Larghetto than Largo which was the tempo indication in the opera. The video score plays back at a tempo of 66 half note or minim beats to the minute. Rests are indicated in the score enabling players to have a clear understanding of the voicing of the musical lines.
Moskowski has also arranged the aria for piano.
